Marcus and Jeff Jordan, sons of NBA legend Michael Jordan, posted on Twitter that they spent $56,000 during one day last week in Las Vegas

Marcus and Jeff Jordan, sons of NBA legend Michael Jordan and current UCF basketball players, posted updates on their Twitter account about their trip to a Las Vegas pool lounge and nightclub with fellow Knights point guard A.J. Rompza.

Patrons must be at least 21 years old to visit both venues, but Marcus Jordan is 20. Jeff Jordan and Rompza are both 21.

Norm Clarke of the Las Vegas Review-Journal is reporting the Nevada Gaming Control Board is investigating underage Marcus Jordan's visit to the pool lounge and nightclub.

Marcus and Jeff Jordan published comments about their visits to Haze Night Club and Liquid Pool Lounge at Aria Hotel and Casino City Center on their Twitter accounts.

Marcus Jordan wrote about spending $21,000 at Liquid. He later wrote about his visit to Haze.

"Last night was stupid," Marcus Jordan wrote on his Twitter account. "... 35k at Haze ... Totals 50k something the whole day ... Damn!! Going to the pool again today ... Gotta relax!"

The Twitter updates have since been removed from his account.

Clarke, of the Las Vegas Review-Journal, reported a source confirmed the Jordan brothers charged more than $50,000 worth of alcohol to their Aria suite. The source told Clarke that Michael Jordan was not with his sons.

Bottle service at Aria is among the most expensive in Las Vegas, with champagne prices starting at about $1,000 a bottle at Haze Night Club.

Marcus Jordan also posted video on his Twitter account of the three basketball players at the Liquid Pool Lounge. Jeff Jordan posted a video of himself inside Haze on his Twitter account, but Marcus Jordan and Rompza did not appear in the short clip.

UCF officials contacted by the Orlando Sentinel on Monday declined to comment about the Jordan brothers' Twitter updates.

Clark reported Friday that Nevada Gaming Control Board member Randall Sayre said MGM International "is in the early stages of an inquiry to see 'where the system broke down.' " Sayre told the newspaper MGM officials would likely report their findings within two weeks.

Marcus Jordan said in an interview with FoxSports.com's Jeff Goodman that he made a mistake.

"I didn't mean it the way it came across," Marcus Jordan told Goodman. "My family and friends know the type of person I am."

Marcus Jordan told Goodman he spoke with his parents about the incident. When FoxSports.com asked how the incident impacted his allowance, Marcus Jordan laughed and responded, "I'm still good."
